not to mention that all the 'impurities' that 'accumulate' over time are generally used by the plants, fish, waterlife as part of their metabolism. Very few things, including heavy metals, don't get consumed in some way. Why do you think our water can have an iron deficiency? Because the plants are using it. I agree; water changes aren't necessary, esp with nature acting on it all the time. But I also agree that water changes aren't going to hurt if you don't change a large amount at one time, you take care of the chlorine issue, and nothing in your source water is toxic to the fish. As you note, rain all by itself 'changes' the water, putting whatever is in the air into your water, changing it that way too.@Turtlehead - we are usually careful to mention that tiny ponds (like aquariums) probably do need some level of water change on a regular basis. I keep a small patio pond (about 45 gallons) during the summer and I generally pull 4-6 gallons out every week or so (use that to water my flowers!) and replace it with water from the big pond. Smaller volumes of water are just generally harder to keep in balance like a larger volume of water. Indoor tanks are a whole different story - you get zero interaction from nature, no natural "fill ups" from rain, no bugs and critters and other help from nature. I've always been of the opinion that the "we must do water changes in our ponds" proponents came straight from the aquarium hobby and brought all their understanding and practices over. As time has gone on, we've learned a lot about how to construct a pond so it's more self-sufficient. The hobby continues to progress!
Fresh water isn't "good" for the fish unless there's something wrong with the current water to begin with. The fact that you have to add water treatment kind of reveals that - there's things in that fresh water (in this case chlorine I would guess) that aren't great for fish at all. Your pond will continually lose water through splashing, evaporation, your filter cleaning, and uptake from plants - you'll need to top it off plenty which should address your concern about concentration of harmful chemicals in the water.
It really doesn't matter to me if people want to do weekly water changes. For me it's just one more chore that would eventually cause me to dread pond keeping. I just think it's important for people to have a place to read that it's OK if you never ever ever EVER change your pond water... ever!
That was a thought i had last year but for some reason i didn’t do it but i will this year.hint I put abs pipe on the bottom of the pond with holes and slits cut in it and it is hooked up to one of the pump hoses and push's the stuff off the bottom of the pond to the filters . I have 2 laguna pumps running so extra sump pump hose goes to the pvc pipes and the abs pipes ,. The more air and the more water moving keeps my pond clean . You can see my spitters and my hoses in my pond build . I have learned to see things differently
more plants, less feeding, or a lot more bog filtratrion (which gives you the more plants option easier and better); remember, small ponds are harder to manage than larger ones...My biggest problem let year was string algae.It was so bad that i couldn’t see my fish. It is easy to remove but it keeps coming back .
Can't find that Pond Build Post?hint I put abs pipe on the bottom of the pond with holes and slits cut in it and it is hooked up to one of the pump hoses and push's the stuff off the bottom of the pond to the filters .
